    摘要： Provided are methods of using fluid loss control additives that comprise a water-soluble polymer with hydrophobic or hydrophilic modification. In one embodiment, a method of providing at least some degree of fluid loss control during a subterranean treatment is provided. In an example of such a method, the method may comprise providing a treatment fluid comprising an aqueous liquid and a fluid loss control additive, the fluid loss control additive comprising a water-soluble polymer with hydrophobic or hydrophilic modification; and introducing the treatment fluid into a well bore that penetrates a subterranean formation, wherein there is at least a partial reduction in fluid loss into at least a portion of the subterranean formation from the treatment fluid and/or another aqueous fluid introduced into well bore subsequent to the treatment fluid.

    摘要： The present invention relates to high porosity propped fractures and methods of creating high porosity propped fractures in portions of subterranean formations. Another embodiment of the present invention provides a method of forming a high porosity propped fracture in a subterranean formation, comprising providing a slurry comprising a fracturing fluid and proppant particulates coated with an adhesive substance; introducing the slurry into a portion of a fracture within the subterranean formation; and, depositing the proppant particulates into the portion of the fracture within the subterranean formation so as to form a high porosity propped fracture. Another embodiment of the present invention provides a high porosity propped fracture comprising proppant particulates substantially coated with an adhesive substance wherein the propped fracture has a porosity of at least about 50%.
